備忘錄三：Spring Boot+Druid+log4j2

一：pom.xml配置：去掉Spring boot 預設的spring-boot-starter-logging，引入spring-boot-starter-log4j2

<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
			<exclusions>
				<exclusion>
					<groupId>org.springframework.boot</groupId>
					<artifactId>spring-boot-starter-logging</artifactId>
				</exclusion>
			</exclusions>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-log4j2</artifactId>
		</dependency>

二：應用配置application.yaml

# logging
logging:
  config: classpath:log4j2.xml

三：log42j.xml配置

四：Druid配置

        url-pattern: /druid/*
        #login-username: admin
        #login-password: admin
#      # 配置監控統計攔截的filters,去掉後，監控介面sql無法統計，'wall'用於防火牆
